YARN-TRAP FOR HOSIERY-KNITTING MACHINES. I

' Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed February 10, 1917. Serial No. 147,775.

- city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Yarn-Trap for Hosiery-Knitting Machines, of which the following is a specification.

My invention consists of an attachment for a knitting machine embodying an eye plate formed with eyes, and a series of ten sion springs having eyes therein adapted to.

register with thoseof said plate so that different numbers or ends of threads or yarn may be guided through the eyes of said plate and said springs, and subjected to the tension of the latter as they are directed to proper parts of the machine, in the manufacturing of stockings or hosiery by the use of two or more threads according to the nature of the stockings.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described.

Figure 1 represents a top or partly sectional view of a portion of a hosiery knitting machine embodying my invention.

Fig. 2 represents a partial side elevation and partial vertical section thereof, on line 22 Fig. 1.

Fig. 3 represents a transverse section of a portion on line 33 Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,

1 designates a carrier ring of a hosiery knitting machine, 2 a frame that supports said ring, 3 yarn carrying fingers which are pivotally mounted on said frame, 4 an angular bracket which rises from said frame, and 5 an eye plate which is supported on said bracket, 6 an oscillating weight, 7 a plate in the base of said ring 1 forming the bed for said weight, and 8 a shear, said plate 7 forming the bed member of said shear, the axes of said shear and weight being on the plate 7, and the latter being sustained b the elbow 9 which latter is secured to the limb 10 of the frame 2 of the carrier ring 1. The weight 6 and shear 8 are pivotally connected with the swinging lever 11 which is mounted on said limb 10, the members thus far described being well known in the art.

Rising from the limb 10 of the frame 2 and secured thereto is the elbow 13 on whose arm 14 are the tension springs 15 which consists of angular shaped plates of resilient metal or other material, the limbs 16 of which are screwed or otherwise fastened to the sides of said'arm 14, while the portions 17 of said plates are set out from the bends or angles 15 of the plates, so as to be salient from the sides of said arm 14 of thevelbow 13, it being noticed that there is a tension spring 15 on each side of the arm 14, and the two springs are located beneath the eyes 19 in the plate 5 so as to register therewith so that thread or yarn passing through said eyes 10 on its way to the knitting mechanism may pass through the springs 15 between the sameand the sides of the elbow 13, the portions 17 of said springs being adapted to yield laterally in opposite directions.

In order to guide said portions 17 of the springs there is passed freely through the same the pin 20 which is firmly secured to the sides of the elbow 13, said portions 17 having therein the elongated slots 21 which receive the end portions of the pin 20, for a purpose to be hereinafter described.

It will be seen that while the threads are running to the needles they play from the plate 5 freely through the spaces between the salient ends of the springs 15 and the arms 14, but when a thread or yarn is to become idle, another finger drops and starts feeding a difierent thread for two or three needles before the first finger raises and carries the thread clear of the needles making it an idle thread.

This thread still held by the last needles into which it is fed, and which are traveling in a rotary motion, is drawn by the needles, through the finger in its new position, which brings it through the tight or closed part of the spring, thereby putting suflicient tension or drag on the thread to make its entrance under the loose weight, and positively between the shears.

The thread now being under the weight and between the shears, which are opened automatically, is cut, and held there until such a time as it may be needed again.

The other threads, however, when not idle are not subjected to the tension of the springs 15 in Which case the salient ends 17 of said springs and the adyacent portions of the arm lt serve only as guides for said threads.

The cross piece or pin 20 prevents the threads While running in operation from outward displacement from the springs upon the movements of the thread or yarn carrytension springs having substantially parallel portions and portions extendingat an angle therefrom With their ends free and having slots, and a pin passed through said slots and-serving to guide the salient portions of said springs, said springs being so located W1th relation to the tension devlce that the said pin prevents the thread from swinging out of operative relation to the tension device upon movement of said"fingers.

2. A thread-tension device for hosiery knitting machines comprising a thread guiding plate, swinging yarn guides, tension springs having substantially parallel portions and portions extending at an angle therefrom With their ends free and having slots, a support to which the parallel portions of said springs are attached, and a pin passed through said slots at an angle to the length of said support and serving to guide said salient portions and to prevent the threads from swinging out of operative relation to the tension springs upon movement of said swinging guides.
